What is the difference between an amyloplast and chloroplast?
Amyloplasts are colorless and you can find them in plant tissues. They do not go through photosynthesis. Chloroplasts are the sites of photosynthesis and energy production.
Why are amyloplasts more prevalent (common) in potato than they are in the elodea cells?
Why are chloroplasts present in elodea but not in potato cells? Do any cells in a potato plant contain chloroplast? Explain your answer.
What was the purpose of the addition of iodine in this experiment? Did iodine increase your ability to see specific parts of the plant cells?
Homework Answers
1) Amyloplasts are cells that store starch (amylose). Starch is a stored source of energy for plants.
Potato tubers are parts of the plant where energy produced during photosynthesis is stored.
Amyloplasts are more prevalent in potatoes because they need to store starch as energy
Eldoa has more choloplasts because these chloroplasts contain chlorophyll which is necessary for photosynthesis. Photosynthesis and sugar production happen in the chloroplasts. Eldoa is a water plant and therefore cannot store starch underground like potato. Therefore it has more chloroplasts to collect more sunlight to perform more photosynthesis.
Potato plant leaves have chloroplasts. This does the photosynthesis to make sugars. This is then stored as starch underground.
Iodine is a compound which stains starch blue black. This allows us to see where in cells and tissues in plants starch is stored.

Photosynthesis and Chloroplasts You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, however. One species of sea slug has found a way to steal chloroplasts, store them in glands lining its digestive tract, and live on the sugar that is produced (Milius, 2010). The sea slug has even commandeered the genes to help repair these chloroplasts to keep them working for 9 months—longer than the algae would (Fang, 2015)! What if...

How Do Chloroplasts Capture Energy from the Sun?
How Do Chloroplasts Capture Energy from the Sun? Plant cells and some algae contain an organelle called the chloroplast. The chloroplast allows plants to harvest energy from sunlight, a process known as photosynthesis. Specialized pigments in the chloroplast absorb sunlight and use this energy combine carbon dioxide and water to make glucose and oxygen. The complete reaction is: 6CO2 + 6H2O + C6H12O6 + 6O2 Raw Materials (Reactants) CO2 = carbon dioxide H2O = water Products C6H1206 = glucose O2 = oxygen Plant cells can...

In this experiment, you will measure the rate of photosynthesis
in isolated chloroplasts using the dye 2,6-dichloroindophenol
(DPIP). The transfer of electrons during the light-dependent
reaction results in the production of H+. This H+ ion can reduce
DPIP, changing its color from blue to clear. The color can be
quantitatively measured with a spectrophotometer. However, in this
experiment, you will qualitatively analyze your data.
